ad-lib
/ˈæd lɪb/
Very CommonA spontaneous or signature vocal sound added over or between a rapper's written lyrics.
Signature ad-libs are part of an artist's brand. Copying another rapper's ad-lib is a subtle diss. Fans will associate specific sounds so strongly with one artist that hearing the same sound from someone else reads as unoriginal.
